Definitions

  • the present invention relates to a method for synchronising an electric machine with an electric grid and an arrangement of an electric machine and an electric grid.
  • a generator will be made, but it is clear that the method and arrangement of the invention may also be used with different electric machines such as in particular electric motors.
  • a synchroniser 3 measures (via measuring transformers 4, 5) the voltage, frequency and phase of the generator 1 and grid 2 and causes a breaker 6 to connect them each other only when these parameters are as close to each other as possible.
  • This difference in phase causes the shaft of the generator 1 to undergo a large torque impact when the breaker 6 is closed, that tends to bring the generator shaft in phase with the grid.
  • the shafts of synchronous machines such as generators are designed to withstand such a large torque impact.
  • the technical aim of the present invention is therefore to provide a method and an arrangement by which the said problems of the known art are sensibly reduced.
  • an object of the invention is to provide a method and an arrangement that let the torque impact on the shaft of the synchronous machine (such as a generator), in case of faulty synchronising, be low and in particular lower than that with traditional synchronising methods.
  • a further object of the invention is that of providing a method and an arrangement that let the synchronous machine shaft be smaller and in general designed so as to withstand lower torque than according to the prior art.
  • the generator 1 driven by a motor (such as but not limited to a gas or steam turbine) rotates, nevertheless it is not connected to the grid 2; i.e. the breaker 6 (for example having three poles) is open.
  • the voltage of the generator 1 is different from that of the grid and its frequency and phases are also different from those of the grid 2.
  • the generator 1 Before the breaker 6 is closed and the generator 1 is connected to the grid 2, the generator 1 must be synchronised with the grid 2.
  • the method for synchronising the electric generator 1 with the electric grid 2 comprises the steps of synchronising the frequency of the generator 1 with the frequency of the grid 2.
  • the synchroniser 3 measures via the measuring transformers 4, 5 the frequency of the generator 1 and grid 2 and drives the generator 1 (via a control line 13) in order to make its frequency equal to that of the grid 2.
  • transformers 4, 5 are shown only connected to a conductor 7 or a single phase of the grid 2; it is anyhow clear that this is a schematic sketch and in different embodiment this connection may be implemented to one or more conductors or phases according to the needs.
  • the voltage of the generator 2 is increased towards the voltage of the grid 2.
  • the synchroniser 3 (via the transformers 4, 5) also measures the voltages of the generator 1 and grid 2 and drives an AVR 20 (Automatic Voltage regulator) via a control line 14 such as to increase the voltage of the generator 1.
  • AVR 20 Automatic Voltage regulator
  • the voltage of the generator 1 is increased up to a first value V 1 lower than the voltage V g of the grid 2, such that at the end of this step a difference ⁇ v exists between the voltage of the generator 1 and the voltage of the grid 2.
  • the phase of the generator 1 is synchronised with the phase of the grid 2 after the voltage of the generator 1 has reached the first value V 1 and before the generator 1 has been connected to the grid 2.
  • the voltage of the generator 1 can be increased up to the original voltage of the grid 2.
  • the first voltage value V 1 is lower than the grid voltage V g by between 5-20% and preferably by between 10-15%.
  • the method of the invention may be implemented using two different measuring transformers 4, 5.
  • the transformers 4, 5 should provide the same secondary voltage (for example 100 V) with different primary voltages (for example, if the grid has 15000 V, the primary voltage of the measuring transformer 4 could be 14000 V and that of the measuring transformer 5 could be 15000 V).
  • the measuring transformers 4, 5 should provide the same secondary voltage with different primary voltages, the primary voltage of the measuring transformer 4 connected to the generator 1 being smaller than that of the measuring transformer 5 connecter to the electric grid 2.
  • the method of the invention may be implemented with the AVR 20 (Automatic Voltage Regulator) provided with or connected to a memory wherein the V 1 voltage is stored.
  • AVR 20 Automatic Voltage Regulator
  • the AVR instead of driving the generator such that its output voltage is as close as possible to the grid voltage V g , drives it such that its voltage is as close as possible to the V 1 voltage.
  • the method of the invention may be implemented with a synchroniser 3 that comprises a control unit 17 and a memory 18 (connected or embedded in the control unit 17) wherein the first voltage value V 1 is stored.
  • the synchroniser 3 can thus compare the generator voltage (measured through the measuring transformer 4) with the grid voltage (measured through the measuring transformer 5) and drive the generator 1 for synchronising its frequency with that of the electric grid 2 and regulating its voltage increasing it towards the voltage of the electric grid 2.
  • the synchroniser (through the control unit 17) causes the breaker 6 to connect the generator 1 to the grid 2 when the voltage of the generator 1 reaches the first value V 1 lower than the voltage of the grid 2.
